There are a lot of great things about installing a turbocharger on your car or truck. The best thing about installing a turbo is, of course, the gobs of power you end up with. Turbo chargers work by forcing air into the engine, allowing you to use more fuel and producing more power. All that pressure can build up and exceed the perfect point of power. That is why all turbo chargers have a pop off valve, such as the Apexi Blow Off valve. With the Apexi Blow Off valve, you can be confident that your engine will not rapidly self destruct with too much pressure. It has a unique twin chamber design that will blow off and will also not generate excessive turbo lag, which is a major hindrance to performance. The Apexi Blow Off valve is not a terribly difficult part to install, especially when considered as part of a larger turbo installation. Like all Apexi components, the Apexi Blow Off valve is manufactured to very high standards, and you can be confident that the Apexi Blow Off valve will protect your engine for a long time.
